摘要： PROBLEM TO BE SOLVED: To provide a battery having uniform current distribution and superior in discharge characteristics at low temperatures or at a high rate by being equipped with a porous high-polymer electrolyte film which has a property of swelling or becoming damp due to a nonaqueous electrolytic solution, and housing at least one of a positive electrode and a negative electrode into the tubular or bag-shaped porous high-polymer electrolyte film. SOLUTION: A tubular or bag-shaped porous high-polymer electrolyte film having a property of swelling or becoming damp due to a nonaqueous electrolytic solution is formed by together fixing respective end parts of two porous high-polymer electrolyte films or an end part of one folded porous high-polymer electrolyte film, by means of thermal fusion, supersonic welding, or adhesive bonding. The porous high-polymer electrolyte film has a porosity of 20 to 90%, and the porous high-polymer electrolyte film is made of a copolymer including polyvinyliden fluoride, polyvinyl chloride, or polyacrylonitrile, or at least one kind of these. The tubular (bag-shaped) porous high-polymer film is formed by together fixing two porous high-polymer electrolyte films 10 (20) at two (three) positions of end parts 12, 13 (22, 23, 24) thereof.

摘要： PROBLEM TO BE SOLVED: To safely insulate a positive electrode from a negative electrode within a battery by blocking the holes of a polymer electrolyte in a specified temperature range in a battery having a porous polymer electrolyte having the property of swelling or/and wetting with a nonaqueous electrolyte, and fixing the polymer electrolyte to the positive electrode and/or negative electrode after the holes are blocked. SOLUTION: In this battery, a porous polymer electrolyte having the property of swelling and/ or wetting with a nonaqueous electrolyte and having a high ion diffusion speed is used. According to this, a battery excellent in discharge characteristic at high ratio or low temperature is available. Even if the battery temperature is raised by any short circuit, the polymer is reacted with the organic solvent or lithium salt in the electrolyte to block the holes of the polymer film, and then solidified between the positive and negative electrodes. Since the polymer electrode acts as an adhesive layer to adhere the positive electrode to the negative electrode, thus, the battery is never led to burning or firing, and it can be said that this battery is safe.

摘要： PROBLEM TO BE SOLVED: To provide a battery in which there is no danger of slippage of a negative or positive electrode out of a holder of a negative or positive electrode current collector. SOLUTION: A tip end made of a copper foil at the upper end of a negative electrode 1a held by a holder 2a of a negative electrode current collector 2 is projected from a window 2b, bent, pressed by a pressing plate piece 2c, and welded by laser welding. Since the tip end of the electrode held by the holder 2a of the current collector 2 is bent and welded, the electrode is hardly slipped out of the holder even if it undergoes vibration or a shock, thus preventing any degradation of battery performance.
